Applicaton filed March 14, 1921. Serial No 452,054,

T0 aZZ whom it may concern:

Be it known tl1at I,SHEBMAN TAYLOR, a citizen of the nited States,residin at Wymore, in the county of Gage and tate of Nebraska, haveinvented a new and useul Door, of which the following is aspecification.

This invention relates to doors primarily designed for use in connectionwith doors of vaults and the like although it is to be understood thatthe improvement aan he applied to various kinds of doors.

One of the objeots of the invention is to provide a door with a combinedsight and ventilating opening whioh is normally closed by a plug, thisplug being removable solely by a person behind the door so that shouldsaid person be locked within a vault it becomes possible for him toremove the plug and thus not only secure the necessary fresh air butalso gives him a view of the ex terior surroundings.

A further object is to provide a plug 01 closure the outer fase of whichis flush. with the corresponding fan-e of the door so that sad plug isnot noticeable from the outs1e.

A still further object is to provide simple and eflicient meahs forfastening the plug in place so that it oannot be removed except bypressure 'rom back of the door.

With the foregoing and other objects in view whieh will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescriloed and claimed it being understood that, within the scope ofwhat is claimed, ohanges in the precise emloodiment of the inventionshown can be made without de parting from the spirit of the invention.

In the accompanying drawings the pre ferred form of the invention hasbeen shown.

In said drawings Figure 1 is an elevat-ion of a portion of the back faceof a door and showing the present improvernents combined therewith.

Figure 2 is a section on line 22, Figure 1.

Referring to the figures by characters of reference 1 designates aportion of a door in which is provided an opening 2 which isfrusto-conical, the said opening tapering toward the back or inner faceof the door.

In this opening is reniovably seated a plug 3 the outer end of whiehlies flush with the outer surface of the door and aan he finished so asto oorrespond therewith and not be noticeable from without. The innerend of the plug is provided with an eXtension 4 having a11 annulargroove 5 and this groeve is adapted to receix e opposed walls of a keyhole slot 6 whioh is formed in a locking plate 7. Said plate is adaptedte bear against the back face of the door 1 and when in engagement withthe extension 41 will obviouslyhold the plug 3 seurely in position.

Should a person be looked in a vault either aceidentally or otherwise itis possible f0 him to push the plate 7 upwardly and re mo"e it from theextension 1. By then pounding on said extension the plug 3 will bedislod ed and will fall outwardly frornthe opening 2. Thus fresh air aanpass into the vault and at the Same time the occupant of the vault willhave a view of thearea in front of the vault. 'The opening alsoconstitutes a loop hole through which the oocupant of the vault aan fireat lourglars who may have olosed the door.

What is claimed is 1. The oombination with a door having an inwardlytapered opening therein, of a tapered plug normall3 se ated intheopening and having an extension at its small end projeeting trom theback or inner faee of the door and means engaging said extension forholding the plug against withdrawal from the opening.

2. The combination with a door hawing an inwardly tapered openingtherein of a frusto-conical plug removably seated within the opening andhaving its large faoe flush with the outer face of the door, anextension upon the small end of the plug having an annular groo"e andmans detaehably seated by gravity in the groove for hold ing the plugagainst removal from the opemng.

In testimony that I claim the foregi ng as my own, I haie hereto aflixedmy s1gnature in the presence of two w1tnesses.
